Wiresharking IEC

Some basic filters for analysing wireshark logs in case of IEC protocols.

IEC60870-5-104

If you use some port other than 2404, then Wireshark will not automatically detect the correct protocol. In this case,

1. select a IEC104 packet from the captured packets list,
2. go to Analyse -> Decode as
3. In the transport tab, select TCP : both ports and protocol 104apci
   

Dispaly packages with TCP length>0 (no ack messages)

tcp.len>0

IEC104 packages

104apci

IEC104 packages (without testframes, S-packets etc)

104asdu

Packets involving 192.168.0.111

ip.addr==192.168.0.111

TCP port 2404

tcp.port==2404

Information object address 401

 104asdu.ioa == 401 

Spontaneous events (COT==3)

104asdu.causetx == 3

Command messages (COT 6, 7, 10)

104asdu.causetx == 6  //Activation
104asdu.causetx == 7   //Confirmation
104asdu.causetx == 10   //Termination

Testframe messages

104apci.utype == 0x10   //Activation
104apci.utype == 0x20   //Confirmation

S-Type messages

104apci.type == 0x01

General Interrogation commands

104asdu.typeid == 100   //Global, Group1...Group16
104asdu.qoi == 20       //Global
104asdu.qoi == 21       //Group1
104asdu.qoi == 35       //Group15
                        Do not use Group 16 GI with Martem devices. This is reserved.

Clock syncronisation commands

104asdu.typeid == 103

IEC61850

MMS: Manufacturing Message Specification GOOSE: Generic Object Oriented Substation Events

Filter IEC61850 packets

 mms 

Display packets involving TCP port 102

tcp.port==102

Display messages containing domain ID "VampRelay"

mms.domainId == "VampRelay"

Display messages containing item ID "VI1GGIO137$CO$SPCSO$Oper" (VI1 control command)

mms.itemId == "VI1GGIO137$CO$SPCSO$Oper"

Display messages containing control commands (Service request 5 = write)

mms.confirmedServiceRequest == 5

Dispaly packets containing message "success" (response to command message)

mms.Write_Response_item == 1
